I'm tempted to get a Raspberry Pi to make a Magic Mirror, https://www.raspberrypi.org/blog/magic-mirror/ . I'm backing the PINE A64 on kickstarter, https://www.kickstarter.com/projects...d-super-comput . For this one I plan to turn it into an Intrusion Detection System (IDS) and throw it on my home network. Unlike the Raspberry Pi's the A64 has gig ethernet and it isn't using a USB bus, so my home network won't overload the poor little board.

Likely as my kids get older we'll do robotic projects with them, and who knows what else.
